Another service provider had already performed a SIT test for this operation three months earlier, but our track record and previous well’s flawless execution convinced the client that the Well Tractor was the tool of choice.
The operation was performed over two runs due to repeated indications of a plug restricting the e-line cable on the first run. On the second run, the Well Tractors were started at 2,720 ft (829m).
Once the lower Well Tractor tagged the Y-tool, the second Well Tractor was engaged and successfully passed the Y-tool at a depth of 3,485 ft (1,062m). Logging was then performed successfully from 7,404 ft to 10,940 ft (2,257 – 3,335m).
The Well Tractor was regarded as a revolution in the industry when it was introduced in the 1990’s. It enables operators to extend the reach of traditional e-line deployment into highly deviated and horizontal wells.
Welltec Release Device (WRD®) is a simple tool which adds versatility and risk reduction to the operation. It provides predetermined locations in the toolstring where it can be parted, should it become stuck.
